Abstract: A database system, method, and computer program product of handling purchases of products is presented, in which the database system comprises a relational database storing relational data for a plurality of products, a key-value database storing a plurality of first files and a plurality of second files, an interface module connecting the relational database with the key-value database, and a shopping engine to communicate with the key-value database. The interface module converts relational data stored in the relational database into first files and second files. The shopping engine queries the key-value database to retrieve available products in response to an availability request.
